I have still yet to upload all the challenge mode levels (as i must complete them all first before having access to their level names,) and i also have not set up full game runs yet either as I'm waiting to see if there's any demand for it or how to set up any autosplits or how it would be timed. But both are planned to come soon.

Hey! Could you set up a full game run leaderboard? Or, could you make me a moderator and I will set it up?

Yea I can gladly make you moderator!
